GOVERNOR-VALVE.

SPECIFICATION forming part of Letters Patent NO.431,406, dated July 1, 1890.

Application filed January 23, 1890- Serial No. 337,812. (No model.)

To aZZ whom it may concern.-

Be it known that we, PETER SIMON and KARL SIMON, of Cologne, in the Kingdom of Prussia and German Empire, have invented new and useful Improvements in Governor- Valves, of which the following is a specification, reference being had therein to the accompanying drawings.

Our invention relates to improvements in steam-regulating apparatus.

The steam -regulating apparatus forming the present application for patent is characterized, compared with other similar devices, by its safe action and its great simplicity.

This apparatus may be applied easily to all sorts of steam-engines.

The construction of the apparatus is shown by the following drawings.

Figure I is a sectional side view Fig. 11, a plan view (without the rotary slide-valve;) Fig. III, a rotary slide-valve in combination with its working-lever, and Fig, IV a plan view of rotary slide-valve.

The bottom plate 13, on which rests the slide-valve A, is lodged within the valvechamber K. Both have a central aperture, which is screw-threaded. Through the bottom plate passes the screw (3, being provided with a conical point, which serves the opposite screw D as bearing. This bearing is adjustable by means of the two screws 0 and D, in order to diminish the friction between the bottom plate B and the slide-valve A, and to ease the latter while under steampressure. The upper surface of the slidevalve is provided with two teeth L, Figs. 3 and 4, gearing with lever F on sh aft G,which latter on rotating turns the slide-valve round its axle D. The rotation of shaft Gis caused by means of lever J ,which is set in to-and-fro motion by the oscillating movements of a ballregulator according to requirement.

7 The bottom plate B, as well as the slidevalve A,are provided with concentric apertures M, Figs. 2 and 4, to admit the passage of the steam, the regulation of the latter resulting through the rotation of the slide-valve, enlarging or narrowing thereby the apertures. To avoid the return-stroke of the slide-valve A, which might be caused by a momentary stoppage of the engine through the steam still resting in the cylinder,tl1e screw E is provided, passing through the cross-piece H, pressing against the bearing on the point of the screw D.

lVllat we claim, and desire to secure by Letters Patent of the United States, is-

111 a steam-regulating apparatus, the combination of the two disks A and I3, situated within the cylinder K, adjustable by means of screws 0, D, and E, the disks being provided with concentric uniform apertures, and of the valve A, hearing on the upper surface two teeth L, gearing with teeth in the lever
